Ionic Network type = null

Question

Iam在Ionic v2 ts中开发一个应用程序。我的network.type等于空。 什么问题？

import { Network } from '@ionic-native/network'; 
 

 

 
@Component({ 
 
    selector: 'page-home', 
 
    templateUrl: 'home.html', 
 
    providers: [ProviderAccessApi] 
 
}) 
 
export class HomePage { 
 
    user : string; 
 
    pass:string; 
 

 
    constructor(public navCtrl: NavController, public providerAPI:ProviderAccessApi, private platform: Platform, public alertCtrl : AlertController, public network : Network) { 
 
     console.log('HomePage carragada com sucesso') 
 
     alert(network.type); 
 
    }

首先请注意，你应该把的this.platform.ready().then(() => {...});内部网络相关的代码时，平台已准备好执行它。

import { Network } from '@ionic-native/network'; 

@Component({ 
    selector: 'page-home', 
    templateUrl: 'home.html', 
    providers: [ProviderAccessApi] 
}) 
export class HomePage { 
    user : string; 
    pass:string; 

    constructor(public navCtrl: NavController, 
       public providerAPI: ProviderAccessApi, 
       private platform: Platform, 
       public alertCtrl : AlertController, 
       public network : Network) { 

     console.log('HomePage carragada com sucesso'); 

     this.platform.ready().then(() => { 
      // Now all cordova plugins are ready! 
      alert(network.type); 
     }); 

    } 
} 

而且要记住，因为它是一个科尔多瓦插件，它不会在浏览器运行应用程序时使用。要使用插件，您需要在模拟器/真实设备上运行应用程序。
